Title: Product with boss
Inventor: NAKANO TAKASHI
IPC: B21D35/00
Filed: 1987-08-31
Abstract: PURPOSE:To obtain a product with a boss by surely forming a boss with pressing by integrally forming a boss with a metal plate stock near the edge part of the metal plate stock and yet forming the metal part for pull-in in an adequate width at a proper angle outside the boss of the metal plate. CONSTITUTION:In the product with a boss having a boss 23 rear the edge part of a metal plate stock 19, said boss 23 is formed integrally with the metal plate stock 19 by pressing, etc. In that case, the metal part 25 for pull-in having the width W within two times the plate thickness (t) of the metal plate 19 is formed ranging over >=180 deg. with the boss 23 as the center outside the boss 23 of said metal plate 19. In case of forming said boss 23 by drawing and burring, in pressing said product with a boss, the material of said metal part 25 for pull-in is thus flowed into the boss 23 effectively and even a comparatively long boss 23 can be formed surely.

Title: Integrated circuit
Inventor: KIOKA RYUICHI
IPC: H01L21/66
Filed: 1990-08-18
Abstract: PURPOSE:To remove defective chips through a quick test by connecting a diode between the substrate and a bonding pad corresponding to one end of a main metal interconnection on a semiconductor chip. CONSTITUTION:A semiconductor chip 1 is provided with a bonding pad 2 corresponding to one end of a main metal interconnection 3, the other end of which is connected to a diode 10. While a first probe 7A is put on the bonding pad 2, a second probe 7B is on a ground pad; the two probes are connected through a power source 8 and a switch 9. When the current flowing through the probes is set at a predetermined value, the main metal interconnection is fused and discontinued if it has a constricted portion, thereby causing the chip to stop functioning. Defective chips can be rejected in this manner.

Title: Outside mirror
Inventor: HISHIKI HIROICHI
IPC: B60R1/08
Filed: 1995-07-25
Abstract: PROBLEM TO BE SOLVED: To eliminate a dead angle, and attain smooth changing and joining of a traffic lane by adjacently installing two mirrors left and right in a mirror part of an outside mirror, and respectively and separately adjusting them. SOLUTION: An outside mirror 1 is composed of an outside mirror cover 2, a mirror 3 and a mirror 4. In the mirror 3 and the mirror 4, an angle is made adjustable by a method similar to a conventional outside mirror. This outside mirror 1 is used in such a way that the mirror 4 is adjusted to a position so far becoming a dead angle or the mirror 3 is adjusted to a usual position to confirm the rearward or the left and the right so that safety can be confirmed by the outside mirror on the position whose safety cannot be confirmed so far since it becomes a dead angle. As a result, an accident can be prevented by eliminating the dead angle even at changing and joining time of a traffic lane.
